ALARM Application filed May'2,

This invention relates to alarm devices and more particularly to deviceswhich cause an alarm to sound when water in a bath tub has reached apredetermined level.

It frequently happens that when faucets in a bath tub are opened to drawwater in the tub, the attention of the operator is diverted andthefaucets are forgotten with the result that the tub soon overflows. Theoverflowing water is always an unnecessary inconven ience and oftencauses considerable damage to the floor and to the ceiling beneath.Vhile a number of devices have been designed to take care of theoverflow of water, such devices at times are ineffective as they donothing to call attention to the fact that the faucets are open and thewater is still running.

It is therefore an object of this invention to provide an alarm devicewhich will cause a gong to sound when the water in a bath tub hasreached a predetermined level.

It is a further object to provide a device which is complete in itselfand which may be readily attached to a standard bath tub.

These objects are attained by an apparatus comprising a hollow metalfloat which will become filled with water when the water reaches apredetermined level. Then the float is filled with water, it sinks. andpulls upon a cord to wind a spring of a mechanism which causes a gong tosound.

These and other objects are attained by the novel construction,combination and arrangement of parts, hereinafter described and shown inthe accompanying drawing, constituting a material part of thisdisclosure, and in which Figure 1 is a cross-sectional side View showingdetails of the device.

Figure 2 is a plan view taken along line 2-2 of Figure 1. q j p Figure 3is a cross-sectional view of a bracket used to attach the device to abath tub. i Y

Referring to the drawings, a bath tub 5 is shown to have the devicemounted thereon by means of a bracket-6, which has integral therewith aweb 7 which supports a tube 8 through which slides a tube 9. The tube 9is" provided with an aperture near its .end through which projects ahookll adapted to engage the. outer end of tube 8. The hook 11 ismounted at the extremity of a leaf spring 12, the latter being attachedto the inner wall of tube 9, V

DEVICE. i928. Serial No. 274,386.

Tube 9 is pivoted at 13 to lug 14 attached toa cylindrical casing 17 anda brace 16 is pivoted to the tube at 15 and the other end of the brace16 isadapted to engage notches in casing 17 to support the casing inadjusted positions.

Mounted diametrically opposite each other on the inner wall of casing 17are a pair of racks 18 which are adapted to be engaged by spring members19 to support a hollow metal float 20, the springs engaging the rackswith a force just sufficient to support the float when the float isempty. l v

A rod 22 passes through the upper end of float and has attached theretoa cord 21. the other end of which is connected to a reel 23 andmechanism designed to wind a spring 24 when the float moves downwards.Mounted on the same shaft as reel 23 is a ratchet wheel 25 which isengaged by a hook at the end of one arm of a bell crank 26, the otherarm of the bell crank engaging a lever 27 to cause the ball 29 at theend of the lever to intermittently strike the bell 28 as the bell crankmoves over ratchet wheel 25.

In operation, when water in a tub reaches a level where it will flowinto the float 20, the float sinks and pulls the cord 21 downward andcauses the spring to be wound. \Vhen the spring unwinds the ratchet 25is roated counter-clockwise to cause bellcrank 26 to cause the lever 27to intermittently strike the bell and sound the alarm. In order to stopthe alarming mechanism from operating, a pawl 30 is mounted on thecasing and adapted to engage a toothed wheelassociated with the spring24.

From the above description, it willbe seen i that I have provided asimple and desirable apparatus for audibly signalling when water in atub has reached a'desired level; The apparatus may be readily attachedto a bath tub and requires no skill to operate it.

The foregoing disclosure is to be regarded as descriptive andillustrative only and not as restrictive-or limitative of the invention,of which obviously an embodimentmay be constructed, including manymodifications, without departing from the scope of the appended claim. I

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is r A device for audibly'signalling whenwater -in a bath tub'has reached a predetermined level comprising acylindrical casing open at the bottom, a pair of racks fixedto the innerWall of the casing diametrically opposite each other, a hollow metalfloat, apair of spring arms attached to the float and engag ing theracks With a force just suflioient to support the float, an alarm devicemounted on the casing above the float, and a cord conneoted to the floatand the alarm device to ac tuate the latter When the float is filledwith Water so that it sinks. 7 10 In itness whereof I have afiixed mysignature.
